If the current (or a future) year is missing from the drop down list used to change your UPS's replace battery date, this is usually because the current date and time on the Network Management Card itself is set incorrectly. The replace battery date year is populated based on the current year. When the date and time is incorrect on the Network Management Card, these options are displayed incorrectly.

The user also will not see a future year available as an option to avoid allowing a user to set a replacement battery date in the future.

Resolution

Update the current date and time on your Network Management Card and then re-check the drop down list to make sure the current year now displays.

To update the date/time on a Network Management Card 1 and 2 (v3.X.X, 5.X.X firmware) via the web interface, go to Administration->General->Date/time->mode.

To update the date/time on a Network Management Card 2 (v6.X.X firmware) via the web interface, go to Configuration->General->Date/time->mode.
